: Distribution of electrons in energy levels, s/p/d orbitals, and electron configurations for atoms and ions.

The (Verification Work No. 1) in O.S. Gabrielyan's 11th-grade chemistry textbook (Basic Level) typically focuses on the fundamental structure of the atom and the Periodic Law. Core Topics Covered

: Writing the full and abbreviated electronic formulas for specific elements (e.g., Phosphorus or Calcium).

: Multiple-choice items focusing on identifying isotopes or determining the number of neutrons/protons.

: Identifying types of bonds (ionic, covalent polar/non-polar, metallic, and hydrogen) and crystal lattice types. Typical Question Structure

Most versions of this work are divided into two variants, each containing:

: Trends in the Periodic Table, such as changes in atomic radius, electronegativity, and metallic/non-metallic properties across periods and groups.
